Missouri becomes the 17th US state to take legal action against the German carmaker over its cheating on diesel emissions, that has led to controversies, one after another.

Separately, Charles Breyer, a US District Judge is ready to hold a hearing on whether to award final approval to a &dollar;10.033 billion worth settlement with 4,75,000 owners of 2.0-litre Volkswagen vehicles.

The suggested settlement would allow owners to sell their polluting Volkswagen vehicles or get them fix, if regulators approve it.

Breyer made public, hundreds of pages of objections from vehicle owners. Many of them claimed that Volkswagen is not offering a good enough buyback price for polluting vehicles made by the carmaker, or repaying them for a few costs such as extended warranties.

Most Volkswagen owners with the affected 2.0-litre engines will get extra compensation of &dollar;5,100 to &dollar;10,000 for selling back their vehicles or getting them fixed.

Missouri's lawsuit will add to the financial uncertainties for Volkswagen from lawsuits filed by state regulators who are seeking monetary fines in addition to any federal or civil claims the automaker will pay.

The 16 other states that have sued the German carmaker over the cheat device include California, New York, Texas, and New Jersey. Washington too lodged an administrative proceeding against the German automaker seeking &dollar;176 million in July.

"Volkswagen's actions demonstrate a flagrant disregard for Missouri's environmental laws, as well as the health and welfare of Missourians," Missouri Attorney General Chris Koster said in a statement on Monday.

VW spokeswoman, Jeannine Ginivan said on Monday the company "is committed to reaching a fair and efficient resolution of remaining federal and state diesel claims in the United States." She said Volkswagen "will review Missouri's complaint and respond appropriately."

Volkswagen has already agreed to pay &dollar;16.7 billion in settlements related to its use of an illegal software to cheat emissions testing.
